Re: HWH Six Pack Manifold Corrosion Repair
Reply #25 –
After reading this thread and the fact that this year my left rear if not fully inflated would self inflate and slowly rise when parked with the leveling system off. My normal procedure after parking is to level the coach and turn off the leveling as in auto sometimes the coach would relevel from us walking around in the coach. But recently due to the L rear problem, I have had to leave it in auto. Decided to order 2 six pack solenoid overhaul kits from Tom McCloud. After I removed the 6 packs to do that, found that the front had some corrosion that might be causing an air leak. After some PM's with Greg, I decided to just order a complete new front 6 pack through FT parts. They didn't have one in stock, so had HWH ship me one direct. When it arrived it also had some corrosion on the nipple side that was not near any of the air line connections. This was a bit disappointing to get a new 6 pack ($781) that already had some corrosion. Called FT parts and sent some pictures. HWH shipped me a second 6 pack along with a return label for the 1st one. Took about a week each time to get the 6 packs. Everything is back together and working fine now, The coach has remained level for a week now with the rear tank holding at 90 psi, so no leaks there. The front still has a slow leak though even with a new 6 pack. I have not been able to find it, but it takes about 24 hrs to leak down to 30 psi.
HWH has made some changes since my coach was built. The new 6 pack has different solenoid coils that are now encased in plastic. Spacing is slightly different for the lower solenoids. It also has 2 T handles on the sides that allow the travel solenoids to be bypassed. I understand this is mainly to be used during coach manufacturing. but can be used to place the coach in travel manually. The new 6 pack did not have the pressure switches, but did have the wiring. Although my coils had a lot of loose rust in most of them from the steel cover, they still worked. I cleaned out the rust and painted the covers. Also found a new washers at Fastenal that were slightly smaller OD, but work. $20 for 10, part # 11103744. There is a thick washer between the coil and the solenoid base and some were rusted beyond cleaning up. Tom McCloud was very nice in letting me return the unused kit, less shipping and handling. I sent Greg my old manifold, in case he might be able to use it as an aid in making new ones. I now have some spare parts and coils. Edit: The 1st new 6 pack did not have the label.
